Letters Patent No. 107,27 9, dated September 13, 1870.

. IMPROVEMENT m tnmrnanacxnrs The Schedule referred to in these LettersPatent aud'making part of the same To whom it may concern Be it knownthat I, RUFUS S. MERRILL, of Boston, in thecount-y of Suffolk and Stateof Massachusetts, have invented certain new and useful Improvements inLamp-Brackets, of which the following.

tions, under which the projecting flange on the lamp passes when thelamp is placed in the bracket, and a spring catch, which, when the lampis in place, snaps over the flange, and holds the lamp-body firmly andsecurely in place.

The spring can be drawn back at any time to release the lamp, whichcan-then be takenoutof the bracket.

v The manner in which my invention is or maybe carriedinto eflect isrepresented in the accompanying drawing, in which- Figure 1 is'aperspective view of the bracket and lamp placed therein.

Figure 2 is a like view of the bracket without the lamp. Thebracket-ring A is lamp-body B will fit in and be supportedby it.

In order to hold the lamp in its place I provide, on the upper edge ofthe ring, inwardly-projccting lugs or fingers a, under which the flangeb of the lamp passes; and, in order to secure the lamp firmly in ofdish-form, so that the" place, I tax to the ring, on the side oppositeto the lugs, a snap-spring, 0, made substantially as shown in thedrawing, so that it will, whenthe lamp 1s putiuto the bracket, snap overthe flange b, and thus hold the 4 lamp-body firmly and'tightly in place.

' Owing which the lamp and bracket are subjected when'the car is inmotion, the spring is the only device WlJlCll will retain the lamp inits proper position.

A set-screw will soon work loose, as, by the constant jar, its tendencyis to unscrew, sothat the lamp will be free to shake about in thebracket, causing the light to flicker, the oil to spill, and renderingthe position of the chimney insecure. The spring, on-thc contrary, atall times exerts a pressure upon the lamp which is unaffected by themotion of the car, and can never be removed unless the spring beforcibly pressed back by the hand, so that the lamp is absolutely assured in its'position, is neverloose in the bracket, and all jar andrattle is prevented.

The bracket-ring A is attached, by a stem, 0, to' a plate, D, which isto be screwed to the side of the car in the usual-manner.

. Having now described my invention,

What I claim, and desire to secure by Letters Patent is r ilamp-bracket,provided with lugs and a spring, for holding securely the lamp in itsplace, substantially as, shown and described.

In testimony whereof I have signed my name to this specification befiretwo subscribing witnesses.
